As above i have a 95 classic sti impreza ticks over really smooth but when accelarating and hitting 3k it pinks a bit and missfires up the revs its just not reving proply and spits back a bit.Changed the coils,plugs,map sensor made no change at all and checked the fault codes which showed nothing.Any ideas appreciated ?

Thanks

My old sti used to do this. I took it to scooby clinic and it was a very small brass "nipple" inside a boost pipe that was causing it. Is this a boost solenoid?

It holds back right up the revs after 3k mate not just a second the whole way
